Additional account assignments in AA - depreciation posting

Dear All,

I would like to use some of the 'Evaluation group' fields in the asset master record as account assignment in AM. (I have created these fields as customer fields in the COBL).

The reason I would like to use the Evaluation Groups as account assignments is that I would like depreciation to be posted to these fields.

Does anyone know if and how I can add these fields to the list of account assignments?

In SPRO (Asset Accounting/Integration with the general ledger/Additional account assignment objects/Activate account assignment objects) I can see the list of objects that I can use as account assignments, however, I do not know how I could add new fields to this list.

Thanks in advance,

Sandor
